The fingerprint chip refers to the chip product with embedded fingerprint recognition technology. It can realize the image acquisition, feature extraction and feature comparison of the fingerprint on the chip. The developer can conveniently realize the function of fingerprint recognition, which greatly reduces the threshold of the fingerprint identification industry. It has a very positive role in promoting the promotion of fingerprint recognition. Compared with the optical systems currently on the market, the fingerprint chip has the following advantages: (1) higher security; (2) small size, can be integrated into other systems: the chip can be embedded in a variety of systems; (3) The cost is low, and the price of chip-based electronic products can be reduced to a very low level when the output reaches a certain scale. From the emergence of the domestic "fingerprint identification chip" to the first true fingerprint identification ASIC, China's fingerprint identification chip technology has experienced a long but tortuous development process. Looking back at this process, we can divide it into three phases: a general-purpose chip with DSP as the hardware platform, a general-purpose chip with ARM as the hardware platform, and the FSC700X series: a chip for fingerprint identification.
